Our verdict
The most complete 1 kWh station we cover: fast to recharge, strong on solar, and expandable when you need more. Pick it unless weight or a lower budget matters more.
Pros and cons
Pros
- 4,000-cycle LFP rating, a step up from the DELTA 2's 3,000
- Full recharge from a wall outlet in 56 minutes, by EcoFlow's figures
- 1,000 W of solar input, double the DELTA 2
- Two 140 W USB-C ports charge most laptops at full speed
Cons
- At 27.6 lb it is heavier than the Jackery Explorer 1000 v2 and Anker SOLIX C1000 Gen 2
- Reaching 5 kWh needs extra batteries, sold separately
- X-Boost runs high-wattage heaters and kettles at reduced power, not at their full rating

The full review
Who it suits
Campers, RV owners and households that want a 1 kWh station today and the option to add capacity later. The 1,000 W solar input means two or three rooftop or folding panels can refill it in a day of good sun.
Who should skip it
Anyone who mainly needs something light to carry to a campsite: the Jackery Explorer 1000 v2 is about 4 lb lighter. If you will never add a battery or solar, the expansion port and the high solar limit are features you pay for and do not use.
What we could not confirm
EcoFlow's US page shows six AC outlets, while its European and Australian pages list four, because regional models differ. We list the US count. One EcoFlow FAQ gives a much higher weight than the product page and manual; we use the product page figure.
